A cleaning apparatus in a waste toner removal system of an image forming device includes a waste toner moving device that is movably mounted in a waste toner housing. The housing has an inlet where waste toner enters the housing. The toner moving device is movable between a first position and a second position to displace accumulated toner within the housing. The toner moving device is spring-biased toward the first position. A rotating actuator displaces the toner moving device from the first position to the second position to move the toner in the housing away from the inlet. The toner moving device is also self-cleaning via vibration and impact movements.

A fuser module of an image forming device including a pivot able end cap and a movable entry guide attached therein. The movable entry guide moves according to the pivoting end cap to ensure reduced positional variability within the fuser module. The pivoting end cap also has a wheel to axle ratio of about 18:1 to ensure reduced force variability within the fuser module.

Embodiments of a pick mechanism for use in an image forming device. In one embodiment, a first mechanism individually moves each of the media sheets from a stack in the input area thereby gradually decreasing a height of the stack. The first mechanism applies a first force profile to the stack while individually moving each of the plurality of media sheets. As the media sheets are moved, the height of the stack gradually decreases from a first height to a second height. As the stack decreases below the second height, a second force profile is applied to the stack. The second force profile is different from the first profile. The first and second force profiles prevent slip as the media sheets are fed from the input area, and also prevent double sheet feeds.

A single-pass color electrophotographic printer includes four imaging stations, yellow, cyan, magenta, and black, on a generally linear path. A toned image in each toner color is developed on an image bearing member or photoconductive drum. A plurality of electrically biased first transfer rollers associated with each imaging station is operative to transfer the developed images from the photoconductive drum to an intermediate transfer member (ITM) belt that travels sequentially past the imaging stations along the generally linear path in a first transfer operation. The image on the ITM belt is transferred to media at a second transfer operation at which the ITM belt passes through a nip between a backup roller and a further electrically biased transfer roller. A servo operation is used to set the voltages on the transfer rollers. Rollers at the second transfer are positioned to direct media downwardly out of the nip to a media transport belt and to a fuser assembly. A reverse roller is provided downstream of the second transfer operation to shift the path of the ITM belt away from the media guide plate and media transport belt. The ITM belt is formed of a resistive material having a uniform thickness and high tensile modulus.

An imaging apparatus includes a machine frame, a printhead housing containing a printhead for generating a laser beam, and a position sensing device. The position sensing device includes a position sensing device frame and a position sensor for sensing a position of the laser beam. The position sensing device frame is interposed between the machine frame and the printhead housing. Each of the machine frame, the printhead housing and the position sensing device frame include at least one reference feature that in combination accurately reference the position of the printhead housing to the machine frame.

A toner cartridge (1) has a single molded element, molded of polystyrene, which is heat sensitive. The molded element forms front handles (3a, 3b) and a cleaner chamber (27) mounts a photoconductor drum (49). A toner hopper (61) is located generally under the handles. A developer roller (43) receives toner from the hopper and applies it to the photoconductor drum. A lower shutter (7) of polycarbonate, which is heat resistant, is mounted on actuating links (13a, 13b). When the cartridge is installed in the printer the actuating links are moved to rotate the shutter to a position covering the lower surface of the cleaner chamber, where it serves as an effective heat shield protecting the cleaner from fixing heat of the printer.

The present invention provides a waste particulate toner collection container system for an image forming apparatus that includes a waste particulate toner spreading device movably disposed within the container in a reciprocating manner generally along its length, the device including a spine member having on a first end a first plurality of spaced apart raking tine members and on a second end a second plurality of spaced apart raking tine members disposed substantially transversely of the length of the spine member, and a crank arm attached at the first end of the spine member. A post disposed on an inner wall of the container supports the device at a point along the length of the spine member between the first and second pluralities of raking tine members, and a drive mechanism is operatively connected to the crank arm for imparting reciprocating movement to the device.
